The 7AN7 is more commonly known as the PCC84 input cascode TV RF stage in VHF Band III television receivers.
In the early days of ITV on Band III in the UK, from Autumn 1955, the viewer would only have had a TV capable of receiving the single Band I BBC station. Adaptation required a new aerial and a converter from the 170 odd MHz of Band III back to the 50 MHZ of the Band I receiver. These original set-top boxes use a two valve line-up with the PCC84 as input and the PCF80 as oscillator and mixer.
One triode anode with the inter-section screen behind.
The thin glass tube envelope is 20 mm in diameter, and excluding the B9A base pins is 48 mm tall.
References: Datasheet & 1040 Type 7AN7 was first introduced in 1954.
